Investors & landlords

You say that I "will allocate the income and expenses if applicable depending on your resident state when you go through the state returns."  This allocation is the point of my question.  I am not asking about how  the states tax the income.  I am asking what buttons I push, what selections I have to make, in order to get the income and applicable expenses allocated away from my resident state and allocated to the non-resident state where the rental real estate is located and is properly subject to tax.  Can you help walk me through the process?
